Sihanoukville has a complicated recent history — a wave of casino development in the late 2010s changed much of the town’s character, and plenty of older travel writing still describes a place that no longer quite matches reality. In 2026, the honest answer is nuanced: the town itself is a mixed bag, but it remains the essential, well-connected gateway to some of Southeast Asia’s most beautiful and genuinely undeveloped islands, and that alone makes it worth passing through.
What changed, and what didn’t
A significant construction boom, driven largely by Chinese investment, transformed much of central Sihanoukville into a landscape of half-finished casino towers and construction sites over the past several years — a jarring contrast to the laid-back beach town it once was. Some of this development has since stalled or slowed, and the town’s character today is genuinely uneven: parts feel like an active construction zone, while Otres Beach, a short distance away, has retained a much more relaxed, traveler-friendly atmosphere.
Why most visitors still come through
Sihanoukville remains the primary ferry departure point for Koh Rong and Koh Rong Samloem, two of Cambodia’s standout island destinations — most travelers treat the town itself as a brief transit stop rather than a destination, spending a single night (or sometimes none at all) before heading straight to the islands. This transit role is really Sihanoukville’s main modern function, and it fulfills it reliably.
Otres Beach: the better base if you’re staying
If you do need to spend a night in the Sihanoukville area, Otres Beach offers a considerably more pleasant alternative to the central town — a longer, quieter stretch of sand with a relaxed beach-bar scene that has largely avoided the casino development affecting downtown. See our Otres Beach vs Serendipity Beach guide for a fuller comparison of the two most commonly discussed beach areas.
Ream National Park: an underrated day trip
For travelers with an extra day, Ream National Park offers mangrove boat trips and genuine wildlife-spotting a short drive from town — a worthwhile addition if Sihanoukville is more than just an overnight stop on your way to the islands.
Should you skip Sihanoukville entirely?
With the expressway from Phnom Penh now cutting travel time to as little as 2-2.5 hours, it’s entirely possible to arrive from the capital and catch an afternoon ferry to Koh Rong the same day, bypassing an overnight stay in Sihanoukville altogether — a genuinely appealing option for travelers who’d rather spend their time on the islands than in the town.
A realistic recommendation
Treat Sihanoukville as a functional gateway rather than a destination in its own right — plan your transport to minimize time spent in the central town, base yourself in Otres if you do need a night, and save your enthusiasm for Koh Rong and Koh Rong Samloem, which remain genuinely spectacular and unaffected by the mainland’s development issues.
Frequently asked questions
Is Sihanoukville worth visiting in 2026?
As a destination in itself, not particularly — but as the gateway to Koh Rong and Koh Rong Samloem, it remains essential for most travelers heading to Cambodia’s best islands.
Is Sihanoukville safe for tourists?
Generally yes for typical tourist activity, though it’s worth reading our dedicated Is Sihanoukville Safe guide for specifics on what has and hasn’t changed in recent years.
Can I skip Sihanoukville and go straight to the islands?
Yes, with the new expressway from Phnom Penh, many travelers now arrive and catch an island ferry the same day without an overnight stay in Sihanoukville.
Where should I stay if I need a night in Sihanoukville?
Otres Beach is consistently recommended over the central town, offering a considerably more relaxed atmosphere with less of the casino-driven construction affecting downtown.
Choosing where to stay if you spend a night
The choice largely comes down to Otres Beach versus the more central Serendipity Beach area — our Otres Beach vs Serendipity Beach guide breaks down the tradeoff in detail, but the short version is that Otres has aged considerably better than the casino-affected central town.
Timing your visit
Season matters more here than in inland Cambodia, since rough seas can disrupt island ferries during the wettest months — see our Best Time to Visit Sihanoukville guide for a full month-by-month breakdown before locking in your dates.
Getting here and moving on to the islands
From Phnom Penh, the expressway has cut travel time to as little as 2-2.5 hours, making a same-day arrival-to-island-ferry connection realistic for the first time. From Siem Reap, the journey is considerably longer and usually routed through Phnom Penh rather than direct.
What to actually do if you have time beyond a transit stop
Ream National Park’s mangrove boat trips offer a genuine nature escape a short drive from town, and the beaches beyond the casino district — particularly the longer stretches south toward Otres — remain pleasant for a relaxed afternoon even if downtown itself doesn’t invite lingering.
A final word on managing expectations
Go in expecting a functional, somewhat rough-edged transit town rather than a polished beach resort destination, and Sihanoukville won’t disappoint — the real reward waits on Koh Rong and Koh Rong Samloem, and the mainland town’s job is simply to get you there efficiently.
Entry requirements before you book anything
Most nationalities can arrive on a Cambodia e-visa applied for online in advance, though a visa on arrival is still available at the airport and land borders for a slightly higher fee. Sort this out early using our Cambodia visa guide, which covers processing times and the documents officers actually ask for.
Where to sleep for your first night
Because the beaches beyond downtown are where most travelers actually want to stay, it is worth comparing neighborhoods before you book. Our Otres Beach vs Serendipity Beach comparison breaks down which strip suits a quiet first night versus one closer to restaurants and the ferry pier.
Coming from elsewhere in Cambodia
If you are routing in from the capital rather than flying directly, our Phnom Penh to Sihanoukville transport guide compares the expressway bus, private car and shared van options along with realistic travel times for each. Travelers crossing overland from Vietnam or Thailand should also check our border-crossing guides before finalizing a route, since some crossings connect more directly to onward transport here than others.
A quick note on safety and comfort
Sihanoukville’s downtown core has changed dramatically over the past several years due to large-scale construction, and safety concerns that circulated a few years back have prompted many travelers to ask before booking. The short answer: stick to the beach areas, avoid wandering the half-built casino zone at night, and treat it the same way you would any transit town — sensible precautions, not avoidance.
